Martin Laursen says Aston Villa go to Chelsea in a "positive mood".

"We are involved in a heavy schedule of games - seven in 21 days - which will end at Chelsea in what to me has become the toughest away match in football," Laursen said.

"Chelsea haven't lost a league match at home for more than four years although they came pretty close against Manchester United a couple of weeks ago.

"There is just no arguing with the fact that they are immense on home soil - but that unbeaten record has to end sometime and we will to Stamford Bridge in a positive mood.

"Don't forget we drew 4-4 there last Boxing Day and I'm convinced that we would have won if Zat Knight hadn't been harshly sent off when we were two-up just before half-time."
